D006: i18n: seven languages + RTL

Context: Saif wants the site in English, Hindi, Kannada (Bangalore), Urdu, Telugu, Arabic, and Hinglish. Urdu + Arabic are RTL; four are non-Latin scripts.

Decision: Build full i18n for all 7 via Astro i18n, per-locale routes, hreflang, dir switching, per-locale Noto fonts. Implementation in Internationalization. Translation mechanism in D007 - Build-time AI Translation.

Why: For this audience (recruiters/clients read English) multi-language is a capability demonstration, which is legitimate under D001 - Site as Proof Principle, i18n + RTL is genuinely hard and signals senior engineering.

Risk / trade-off (important): quality is binary, fluent Urdu/Kannada impresses; sloppy machine output hurts the signal. Mitigation: English is canonical; each locale ships live only after a review pass. Launch scope + reviewers open (Open Questions #4). RTL handled via logical CSS (Design System).
